Application of resampling techniques to the statistical analysis of the Brier score

We investigated the application of resampling techniques to the statistical analysis of the Brier score (B), and extended them to the statistical comp arison of two Bs derived from the same set of patients. The resampling tech niques are helpful in the statistical analysis of B, and there are almost n o differences between the jackknife method and the bootstrap method in this analysis. Thus, we believe that B should be used more often as an index to evaluate probabilistic judgments in the case in which the data sets for th e assessment are "degenerate" as the "receiver operating characteristic dat a sets."
